general explanation of "diversity"

You'll notice that lots of access points, and some cards (like the Cisco) have 2 antennas. These antennas aren't used at the same time. The radio rapidly switches between the two to find the strongest signal. What happens is that the radio waves bounce around on things and you get what is call "multipath interference" (like ghosting on non-cable televisions). A small distance change in antenna placement can lessen or eliminate multipath interference and that is what antenna diversity attempts to do.
